Dr. Marty Bax (1956 Montreal, Canada) is an art and cultural historian. In 2004 she received her PhD on an interdisciplinary study on the relationship between art, social culture and Western Esotericism in the Netherlands. She is specialist on the work of Piet Mondrian, the pioneer of non-figurative abstraction, has organized numerous international exhibitions and has been an art critic for Het Financieele Dagblad (the Dutch Financial Times) from 1987-2014. In 2020 she was contracted by the Claims Conference (Conference on Jewish Material Claims Against Germany) as the expert provenance researcher on the plunder of books and archives by the Einsatzstab Reichsleiter Rosenberg (ERR) in the Netherlands. The ERR targeted all volksfeindliche organizations: Jews, friendly societies (Freemasonry, Order of odd Fellows, Rotary etc.), western esoteric organizations (Rosicrucians, Theosophy, Anthroposophy etc.), and communist, socialist, feminist and utopian groups. From the start of the deportations of Jews in March 1942, the ERR gained supremacy over all plunder activities. In the Netherlands 107.000 of the total Jewish population of 140.000 (including fugitives) was deported – the highest percentage in Western Europe. Preliminary results will be published shortly on the website https://errproject.org/.
